SUPPORTING MEANS FOR MOTORS.

Specification of Letters Patent.

Patented July 22, 1919.

Application filed November 18, 1918. Serial No. 263,104.

T 0 all whom it may concern Be it known that I, JOSEPH IV. NELSON, a subject of Sweden, and a resident of St. Cloud. in the county of Stearns and State of Minnesota, have invented a certain new and useful Improvement in Supporting Means for Motors, of which the following is a description, reference being had to the accompanying drawing, which forms a part of my specification.

My invention relates more particularly to means'whereby the motor is suspended from, or secured to, the chassis of an automobile; the invention having for its object the provision of flexible or yieldable means whereby the motor is supported so as not to be subjected to the twisting strains encountered by the chassis of an automobile and yet at the same time securely support the motor on the chassis so as to mamtain the proper posltlon thereof and in no way interfere with the driving mechanism of the automobile.

My invention contemplates what is known as a three-point suspension for the motor, wherein two of said points are usually of a rigid nature, between what may be called the rear end of the motor and a cross-menu ber of the chassis; while the other or thirdpoint of suspension or support is at the forward end of the motor, at a point intermediate of the sides; said-last-mentioned or third point being of a yielding nature which will permit the side members of the chassis to have different, independent movement, without, however, transmitting said unequal movements or twisting strains through said third point of suspension to the motor-casing.

The object of the invention and its advantages will be readily comprehended from the following detailed description of the drawing, wherein Figure 1 is a front elevation of a portion of the motor or casing and portion .of the cross-member of the chassis, with my improved means applied thereto.

F ig. 2 is a sectional view taken on the line 22 of Fig. 1. e

In the particular exen'iplification of the invention, the rear end of the motor may be supported and secured in place on a crossmember of the chassis in the usual manner, and therefore only a portion of the forward end of the motor-casing is shown at 5,

through which the forward end of the crankshaft 6 is disposed; the forward end of the crank-shaft being provided with the usual clutch or engaging surfaces adapted to be engagedby the toothed stub-shaft or cranking shaft 7; the latter being suitably mounted in a bracket 8 supported by the forwardly presented lugs or flanges of the motor-cas'-.

ing; said stub-shaft or cranking shaft 7 being held in retracted or disengaged position by means of the usual coil spring 9. The chassis is provided at the forward end thereof with the usual cross-member ll), which is bowed -downwardly intermediate of its ends, as shown in Fig. 1, in the usual manner.

The motor-casing 5 at the lower end is provided with the forwardly presented lugs or continuous flange 11, provided with suitable apertures for the passage of bolts 12, 12 which are secured in place by means of the usual nuts 13.

Instead of securing the motor-casing directly to the cross-members or frame 10 of the chassis, I support the motor at the forward end through the medium of a suitable element preferably-comprising a suitable number of flat'steel plates or leaves 14. The plates are preferably identical in thickness, length and width and superposed as shown,

with the ends provided with holes for the passage of the bolts 12,-12 whereby said plates or leaves are maintained in superposed relation and securely bolted to the lugs or continuous flange 11 of the motorcasing.

At a point intermediate of the ends of the steel plates or leaves 14, the latter are all bolted to the cr issaneniber 10'-of the chassis by means of bolt 15 which is secured in place by a nut 16. The steel plates or leaves 11, however, are not brought into contact with the cross-men'iber 10 of the chassis. but are supported by or have bearing on a pad or block 17 which rests on the cross-member of the chassis. The ad or, block 17 is made of less length'than tie steel plates or leaves 14, as clearly shown in Fig. 1, so as to permit with a slightly arcuate upper surface or beveled ends, as shown in Fig. 1, so that the ends of the pad or block will not be in intimate contact with the lower plate or spring 14, thus allowing greater movement between the chassis and the forward end of the motor.

It is evident from the construction shown and described that the twisting strains to which the forward part of the chassis is subjected during the operation or travel of the automobile, will be transmitted to and taken up by the yielding means 14 composed of the superimposed spring plates or leaves 14:, which will flex upon themselves and about the pad or block 17 and thus prevent any fracture of or damage to the motor-casing and its supports or fastenings. The ends of the springs for the passage of the bolts 12, 12 are, of course, suitably apertured so as to permit the desired flexure of the superimposed spring plates or leaves 14 of which any suitable number may beemployed in superposed relation, commensurate "with the weight of the motor so as to normally maintain the proper alinement of the motor with the points of suspension at the rear end of the motor-casing.

. The specific construction of the invention, as disclosed in the drawing, may be modified in certain respects without, however, departing from the spirit of my invention; as, for example, instead of making the pad or block 17 as a separate member, it may constitute an integral part of the cross-member of the chassis formed so as to provide a suitable bearing for the resilient means disposed intermediate of the motor-casing and the cross-member of the chassis; and the invention may be applied to the other situations; and I do not wish, therefore, to be under- 'stood as limiting myself to the exact construction shown and described, but what I claim and wish to secure by Letters Patent 1. Supporting means of the class described, comprising, in combination with the motor-casing and cross-member of a chassis, flexible means disposed intermediate of the motor-casing and the cross-member, said means being secured to the motor-cas- 'ing and said cross-member at, different points, and means adapted to bear against said flexible means at a point intermediate of the ends thereof so as to permit said first means to flex about said second means;

2. Supporting means of the class described, comprising, in combination with the motor-casing and cross-member of a chassis, flexible means disposed intermediate of the motor-casing and the cross-member of the chassis, and a pad or block secured to the cross-member and to said means at a point intermediate of the ends thereof, while the ends of the means are secured to the mo tor-casing.

3. Supporting means of the class described, comprising, in combination with the motor-casing and cross-member of a chassis, flexible means disposed intermediate of the casing and cross-member, and a pad or block adapted to bear against the means at a point intermediate of the ends thereof, said means being secured to the motor-casing and said cross-member at different points so as to permit said means'to flex about said pad or block.

4. Supporting means of theclass described, comprising, in combination withthe motor-casing and cross-member of a chassis, a plurality of superposed flat spring plates secured to the motor-casing and crossmember but at different points, and a hearing member adapted to contact with the adjacent plate at a point intermediate of the ends so as to permit the plates to flex about said bearing. member.

5. Supporting means of the class described, comprising, in combination with a motor-casing and a cross-member of a chassis, a plurality of superposed flat spring plates, the ends whereof are adapted to be secured to the vmotor-casing, and a bearing pad or block adapted to be secured to the cross-member and to said plates at a point intermediate of the ends of the plates, the- JOSEPH W. NELSON.
